Unless they are a very enlightened management upstairs, the approach by the 3/4 Captains will do no good. It is more likely to provoke a response of "We won't be held to ransom by bloody pilots just because there is a shortage. Taking advantage of us, that's what they are doing, the bastards. If we give in to them, we will have them all demanding more. Wait till it all turns around next week, they will be back in line - just wait and see" rant rant, beat chest etc.
